UNITED-STATES PATENT OFFICE HENRY GOODMAN, OF ST. LOUIS, MISSOURI, ASSIGNOB OF ONE-HALF HIS RIGHT TO DANIEL P. KANE, OF SAME PLACE.

IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specificationforming partof Letters Patent No. 212,459, dated February 18, 1879; application filed December 5, 1878.

To all whom it may concern:

Be it known-that 1, HENRY GOODMAN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Breech-Loading Fire-A1-ms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The first part of my invention consists in. providing the breech end of the barrels with a stop device which shall extend directly back from and in line with the barrels, and form a part of the breech-frame, said stop resting against a top plate at the top of the breech on the barrels being tilted by the operation of a hinge of peculiar construction working in a tion at x m, Fig. 3,- the barrels being in the.

loading position. Fig. 2 is a similar -view, showing the barrels in firing position. Fig. 3 is an under detail view, with part in section toexhibit the hinge set-screw. Fig. 4 is an end view of the breech-frame, the barrels being removed. Fig. 5 is a detail-top view. A is the breech-frame, having a portion, B, extending forward beneath the barrels O, as

- usual. The part Bis made with a longitudi nal slot or slit, b, to allow the hinge-ears b to be sprung inward upon the hinge-lug 0 ot the barrels, so as to cause the proper amount of friction inthe hinge, and insure perfect accuracy in the movements of the parts when the barrels are moved from the loading to the fir.- ing position, and vice versa.

To adjust the ears b. asabove, the pintlepin D has a setscrew, (1, and a head, (1, which bear against the outside of the ears. Thus, by the turning of the screw, the ears are adjusted. Y

The stop-lug c is made separate from the hinge-lug a, so as to give a better bearing in the breech-frame, each lug fitting snugly in its proper recess, and insuring the accurate position of the barrels upon the breech-frame.

My invention does not apply to the manner of connecting the barrels and breech-frame,

except as to the adjustable featureofthe ears. b and the stop-lug 0, so that particular description of other parts will be superfluous.

The hinge-lug 0 may, however, as a modification of the above construction, extend back farther than the breech end of the barrels, and thus form the stop-lug, whichywhen the barrels are in the loading position, (shown at Fig. 1,) rests'against the top plate, a, and limits the movement of the barrels upon the hinge b c D.

I place between the platen and stop lug or" projection c a spring, E, to ease the impingement of the stop 0, projecting against the plate a. I

The purpose of the stop a is to prevent the straining of the hinge b c D by the falling of the barrels into loading position. Such strain is very liableto occur, and any strain or wear of thejoint causes the parts to come together in an improper position, and the result is uncertainty of aim and danger to the person using the gun; r

F F are tongues entering recesses in the breech-frame when the barrels reach their firing posit-ion.

I claim as my invention- 1. The stop-lug c on the barrels, extending directly back of and in line with the barrels,

top plate, a, and hinge b c D, substantially'as and for the purpose set forth. h

2. The combination of the stop-lug a on the barrels, top plate, a, and spring E, secured at one end to the under side of said top plate, its

free end being adapted to. receive the impact of the stop-lug, substantially asset forth.
